I is for igneous
Ice cap: a smaller body of ice (less than 50,000km squared) usually found in mountainous regions
Ice sheet: a large body of ice over 50,000 km squared in extent
Ice wedges: cycles of freeze-thaw weathering on the soil causes cracks to expand
Igneous rocks: formed from the cooling of molten magma
Immediate responses: how people react as the disaster happens and in the immediate aftermath
Immigrant: someone entering a new country with the intention of living there
Impermeable rock: a rock that does not allow water to pass though it
Incineration: getting rid of waste by burning it on a large scale at selected sites
Industrialisation: a process, usually involved in the development of an economy, where an increasing proportion of people work in industry
Infant mortality: the number of deaths of children under the age of 1 year expressed per 1,00 live births per year. It is useful s a barometer of social and environmental conditions and is sensitive to changes in either
Infiltration: the passage of water into the soil
Informationalisation: the increasing importance of the information-based sector of the economy which relies on the electronic transfers
Inner city: the area around the CBD – usually built before 1918 in the UK
Inputs: anything entering the farm system, e.g. climate, soil, seed labour
Instability: unstable atmospheric conditions leading to rising air frequently associated with cloud formation and precipitation
Intensive farming: high inputs of capital and/or labour to achieve maximum productivity
Interception: the process by which raindrops are prevented from directly reaching the soil surface
Interdependence: the relationship between two or more countries, usually in terms of trade
Interglacial period: a period of ice retreat associated with rising temperatures
Inter-locking spur: spurs are large sides of valleys that stick out into rivers. These are bulldozed as a glacier moves down its valley
Inter-tropical convergence zone (ITCZ): a result of the heating of the part of the Earth’s surface, caused by the concentrated insolation from the overhead sun. This leads to heating of the air lying on that surface. The heat air becomes less dense and rises. This draws in cooler air that flows across the surface to replace the rising air. Air streams are drawn in form both north and south of the equator and they meet in the area from which the air is rising
Intrusive rock: igneous rock formed by the crystallisation of magma below the surface of the Earth
Irrigation: The artificial application of water to the soil. In crop production it is used mainly to replace missing rainfall in periods of drought
Isostatic lift: uplift of a land mass resulting from tectonic processes
